Original No.` 1,600,723, dated September 21, 1926,` Seriall No. 84,246,led January 27,1928.V Application for reissue led June' 25, 1927.SrialNo. 201,547.

lMy`` invention relates to a paint composition and also yto the processof applying the composition to the surface to betreated in a manner toprovide an artistic finish,lit more particularly relating to acomposition and processA of vapplying the same which will `result in afinish havin numerous cracksor net work of fissures, w ich result in adesign known as the crackle effect or craze finish.

The object of my invention is to provide a very simple composition andprocess of applying the same which will result in a finish havingnumerous cracks or, fissures forming various designs of an artisticnature.-

Fig. 1 is a plan view of the crackle finish. l

Fig. 2 is a sectional view of same. There is illustrated onl .o neparticular aving numerous cracks or fissures, the process beingsusceptible of forming many and various designs of this crackle finish.f

To that end the invention consists 1 n providing a composition which isapplied in `tvvo coats having different drying c aracteristics in thatthe undercoat dries slower than the outer coat, therebyl7 causing theouter coat to slip or move on t e under coat so as to produce checks orcracks which result in' peculiar designs of an artistic nature.

For the under coatI ,preferably .use what is known as gloss oil whichconsists of ordinary painters varnish mixed with' rosin in about theproportions of 50% benzine, 9

linseed oil1% oyster shell, and 40%-ros1n, which is in effect an elasticbase.

For the outer coat, I-preferably employ the following ingredients mixedsubstan- 0 tially to the proportions stated for a given quantity ofmaterial: 1/2 pt. wood alcohol, 1/2 pt. denatured alcohol formula No. 5,V2 oz. highly refined benzine, Si@ lbs. lead carbonate or ordinarywhite. lead.

The under coat is of a character that will dry slower than the outercoat, as the alcoholand benzine will vevaporate rapidly from the Ileadcarbonate, and this difference in drying characteristics causesrthe leadcarbonate to slip or move on the under/coat of varnish and rosin, which'movement of the outer coat causes it toV check or crack in a manner toform arbitrarydesigns of various kinds'.`

The composition may be applied -to any u surface upon which the desiredeffect is to be 4. sire'd coloring matter, may be added -plying theouter coat.

secured such as interior walls and any 'deto the iriigredients of theoutercoat. The artistic e ect may be produced with large cracks or-Avery small cracks or fissures, this depending upon the way in which.the outer coating is applied, either lightly or heavily, and the designmaybe changed by changing the method of application, i. e. by app yingthe i outer coat by vertical strokes of the brush instead of applying itby horizontal strokes of the brush. To that end, what has 'been called`the outer coat may be applied by one or more applications, and ifdesired, what has been called the under coat ma be also made in one ormorea'pplications o the varnish and rosin, and it is only necessary tolet the under coat stand a. short time before ap- It will only requirea, short time for the under coat to become .sufliciently smooth and hardto apply the outer-'coat to the best advantage and very soon thereafterthe outer coat will begin to lslip upon'the inner coat and this outercoat being of a lasticcharacte'r, the ridges and grooves wi l beirregular in character and portions thereof will necessarily be squeezedor kneaded vinto raised or embossed surfaces.

lIt is to be understood that with changes in atmospheric conditionsthere will be correspondin .changes in the method of application 'an theexact proportions of the ingredients, but I have endeavored toillustrate the composition of the materials and, the method ofapplication suitable for a plication under normal atmospheric con jtions. Any one versed in the art will quickl 1y learn by experience howto4 obtain the best results under any and all atmospheric conditions. 'f

Nothing set forth and claimed in the divisional application Serial No.117,242 filed June 21, 1926, is hereby waived. 4 Having thus describedclaim as follows: 1. .The method of applying a finish toa surface,consisting in applying to the sui'- `face two distinct liquid coatingshaving different drying characteristics, the first coating stan ing ashort time before appl ing thesecond coating, the under coating aving alrelatively smooth surface and .the outer of a plastic character, thedifferences in the drying characteristics of the two coat-A my yinvention, Iv 10 ings being such as to cause the plastic coating to'slipupon the under coating causing portions of the lastic coat to assume araised or embosse character. y

2. The method of a plying a finish to a surface consisting in rstapplying lto said surface a liquid coating of an elastic base, allowingbSallie to stand a short time and thereafter applying an outer coatingof plastic character, the two coatings avm dierent dryincharacteristics, the under coatingbeing s ower to dryl than'the outercoating' whereb the outer plastlc coating will slip upon t e undercoatlng.

3. The method of producing an artistic finish to a surface consisting inapplying to ysaid surface a liquid composition of a character that willquickly acquire a smooth and thereafter applying an outer coat of aplastic character, the two coats having diflferent dryingcharacteristics, the under coat being slower to dry than the outer coat.

` 4'. The method of producing an artistic finish to a surface consistingin applying to said surface a liquid composition comprising' a mixtureof varnish and rosin, allowing same to stand a short time, then applyingto said surface another liquid composition comprising a mixture of whitelead with alcohol and benzine having the characteristic of drying fasterthan the first composition.

In Witness whereof, I have hereunto subscribed my name.

CHARLES H. EGELHOFF.
